Gateway Ticketing  (2019-present)

Gateway has a focus on amusement parks, water parks, museums, zoos, arboreta and ferry systems. Their primary offering is an application, Galaxy, built using Delphi, for which I initially helped write tests (in Delphi and C#).

Currently, I am a developer on the web team, creating new Selenium tests (C#) for the product which is a remarkable learning experience!

I have also created and maintain an administrative toolkit (Powershell) for web developers and QA/TA staff to quickly create, upgrade and manage multiple webstores, Galaxy environments and associated databases and services.

Gateway is an awesome employer!

Sustrana (2016-2019)

I was a developer on 2-3 person team, building a SaaS with curated education and unique tools to help businesses evaluate their market position, focus on key issues, set SMART goals, develop actionable strategies, establish metrics, manage projects and collect/report data to demonstrably improve sustainability in five areas: Environmental, Social, Governance, Business Model and Management.

At Sustrana my roles were diverse.  Business analysis, tool design and mockup (Balsamiq/Moqups), coding (Visual Studio; ASP.Net, HTML, CSS, Less, JavaScript with Knockout for two-way data-binding; Amcharts, vis.js, Highcharts for graphics), testing, blog writing and communication with clients to resolve technical issues were all part of a day.


I taught myself to code by dreaming up interactive pages to extend my student’s learning and hopefully enjoyment of science.  StackOverflow, Udemy, Udacity and Coursera were my buddies on that journey.


Before software development, I taught science for twenty years, at three venerable institutions in and near Philadelphia:

The Agnes Irwin School (2007-2016)

As Science Department Chair (2012-2015), I coordinated, collaborated with and supported the work of eleven faculty teaching 22 courses across all three divisions (LS, MS and US) and in the development and implementation of numerous academic and extra-curricular programs.

I taught Earth Science (8th grade) and AP Environmental Science (11th and 12th grades)

Created three Special Studies Programs (a signature program of AIS) for 10th and 11th graders: Discover The Schuylkill Watershed, Sustainable Farming: Seed to Table, and Alternative Medicine.

The Schuylkill Center for Environmental Education (2002-2007)

As Director of Education (2004-2007), I interfaced with the regional environmental community in the Philadelphia region to further the Center’s onsite and outreach programs, including the planning, writing and implementation of many grants from the EPA to individual grantors. I coordinated the Center’s partnership with Arcadia University to offer courses leading to graduate degrees in Education and PA certification in Environmental Education K-12. Led the Center’s work with GreenWoods Charter school (during this period the school was housed at and in partnership with SCEE), developing with my colleagues science lessons in the context of the Center’s 350 acres for grades K-8, and working with the classroom teachers to ensure that we met the PA Standards for Environment and Ecology.

Environmental Educator (2002-2004) for thousands of schoolchildren, scouts and others visiting the Center for day and overnight experiences on scores of topics relating to ecology and sustainable development.

The Haverford School (1996-2001)

I taught Conceptual Physics (9th grade) and AP Biology (11th grade)
